To do...
Specify the
protocol(s)
If you have configured a user interface to support SSH protocol, you must configure AAA
authentication for the user interface by using the authentication-mode scheme command to
ensure successful login.
On a user interface, if the authentication-mode password or authentication-mode none
command has been executed, the protocol inbound ssh command is not available. Similarly, if
the protocol inbound ssh command has been executed, the authentication-mode password
and authentication-mode none commands are not available.
Configuring the SSH Management Functions
The SSH server provides a number of management functions to prevent illegal operations such as
malicious password guess, guaranteeing the security of SSH connections. You can specify the IP
address or the interface corresponding to the IP address for the SSH server to provide SSH access
services for clients. In this way, the SSH client accesses the SSH server only using the specified IP
address. This increases the service manageability when the SSH server has multiple interfaces and IP
addresses.
Follow these steps to configure SSH management functions:
To do...
Enter system view
Set the SSH authentication
timeout time
Set the number of SSH
authentication retry attempts
Configure a login header
Specify a source IP address for
the SSH server
Specify a source interface for
the SSH server
Use the command...
supported
protocol inbound { all |ssh }
Use the command...
system-view
ssh server timeout seconds
ssh server
authentication-retries times
header shell text
ssh-server source-ip
ip-address
ssh-server source-interface
interface-type
interface-number
Optional
